In remembrance of Pearl Harbor.
One of the airplanes under restoration at the Smithsonian National Air and Space Museum Steven F. Udvar-Hazy Center is a survivor from the 7 December 1941 Japanese attack on Pearl Harbor. It is a Sikorsky S-43/JRS-1 flying boat built in 1938 and used by the U.S. Navy. It survived the attack, and spent World War II hunting for Japanese submarines in the Pacific Ocean, a task for which it was armed with depth charges. It was retired in 1944.
